The mechanism of a recently reported, highly chemoselective metal-free protocol of wide general applicability for the reduction of aromatic and aliphatic nitro-derivatives to amines has been investigated. The reaction is supposed to occur through the generation of a Si(II) reducing species; quantum mechanical calculations, and spectroscopic and experimental data strongly suggest the tertiary amine-stabilized
研究了最近广泛报道的高度化学选择性的无金属方案的机理,该方案对将芳族和脂族硝基衍生物还原为胺具有广泛的通用性。该反应被认为是通过还原Si(II)物种而发生的。量子力学计算以及光谱和实验数据强烈表明,叔胺稳定的二氯甲硅烷基是最可能的还原剂。
